I've been hoping to be able to access large amounts of memory on affordable servers for a while, in reality, though, the 4GB OS limit has hardly been the issue since unfortunately the cost of memory is still very high and hardware vendors seldom offer more than 4GBs per processor. The Sun Opterons are the only ones (among the mainstream vendors) that offered us a 4-way option with 32 GBs. The Apple G5s are still limited to 8GB (4 per processor, probably when Tiger will be truly released they will finally offer more memory slots?), IBM Opterons offer 16GB (still only 4GB per processor), the blade versions are always limited in memory, etc... then you are left with the usual suspects (Power5s, etc.) who have been dealing with more memory for a long time, but at a nasty price... ...as long as it costs more to equip hardware with good amounts of memory than it costs to buy the hardware, the refinement of 64-bit OS for access to large amounts of memory can't take off properly, can it?
